P2T: Pay to Transport

We present Pay To Transport (P2T), a protocol that lets customers buy an item remotely in an atomic, privacy preserving and trustless manner. P2T needs only basic features of a blockchain scripting language and does not need any tracking systems, arbitrator or deposit to preserve its security properties. For this reason the protocol can be implemented on any permissionless blockchain, regardless of its scripting language, without additional trust. Merchants’ and transporters’ addresses are public, but in P2T the parties never pay those addresses directly. Therefore P2T maintains the privacy of customers, merchant and transporters.
